Call generator

This module is intended to be used for load testing. It can generate large number of calls originated from Yate on an arbitrary protocol or to some number.

The call generator can be controlled from the rmanager as it processes "engine.command" messages or from Yate's command line.

How to use callgen from command line

Callgen messages can be generated from Yate's command line like this:

yate 'callgen set called=1234' 'callgen start'

or something like this:

yate 'callgen set callto=sip/sip:1234@gw' 'callgen start'

Commands

callgen set paramname=value

Sets the value of parameter paramname to value.

callgen set paramname

Display the current value of the parameter paramname.

callgen info

Display statistics about the current call session:

total calls made

how many got ringing

how many got answered

number of running calls

number of calls left to make in the current session

callgen start

Start the calls generator.

callgen stop

Stops the call generator and drops all current calls.

callgen pause

Pause the call generator - do not generate new calls. Current calls continue to completion.

callgen resume

Resume generating new calls.

callgen drop

Drop all current calls but continue to generate new ones.

callgen single

Make a single call.

callgen load

Load the parameters.

callgen save

Save the parameters.

Important parameters

The following parameters are relevant:

callto

Location to call, should be something like sip/sip:user@ip. It takes precedence over called

called

Called number to use in routing. It is ignored if callto is set.

caller

Caller number to use in calls.

source

Data source to attach to the outgoing call. You can use something like tone/ring

maxlife

Maximum lifetime of the call in milliseconds. If not set it defaults to 60000 (one minute).

minlife

Minimum lifetime of the call in milliseconds. If set calls will have a random lifetime between minlife and maxlife.

numcalls

Number of calls to generate in this session, default 100.

maxcalls

Maximum number of simultaneous calls, defaults to 5. The actual number depends on how fast the calls are generated and destroyed.

avgdelay

Average delay between new calls in milliseconds. Defaults to 1000. If the current number of calls falls below maxcalls a new call will be generated after a time randomly distributed between 0 and 2*avgdelay.
